How to use C Caller block with C code having multiple functions ?

I want to use a C language code into simulink which has multiple functions in it. Can it be done by C Caller block.

The C Caller block can only call one function. You can either use a seperate C-Caller block for each function, or write a wrapper C-function that calls multiple functions and then call that wrapper C-function from the C-Caller block.

Can you explain this in detail, how to call that wrapper c cfunction in c caller?

I have only 1 c file, but 2 functions inside that, so can I use one c caller block to implement 2 c functions at a time? If yes, can you explain how

[Mark McBroom]

The C Caller block can only call one function. You could use two C caller blocks, one for each function, and then place the 2 C Caller blocks inside a subsystem ... or you can use the C Function block and call both C functions from the single C Function block.

Okay , thank you for clarifying my doubt. whether s function block can call 2 functions inside one block?
